My car is 96'Suzuki Sidekick Sport, 1.8l engine with more than 10k.

that rumor you are repeating of from the old days, 1960s ? and was a rumor than back to the 1930s' when they used alcohol then.
your engine is must run at 180f, (like it did new)
the antifreeze word (simple) is just lie here is what it really is.

the engine coolant, does 2 things, and more.

it prevents freezing, (check) at 50% mix, the freeze point is near -30degress F, note the minus sign, that is near 60degress bellow freezing temp of pure water +32F. huge protection.

it increases greatly the cooling liquid to conduct (transfer) heat from the water jacket and to the Radiator , THIS IS NOT OPTIONAL on any modern car, this.

so is ANTI-Boil over protection of 50% mixed coolant too. 260F protection.

and last? is it prevents rust and fast corrosion inside the engine. never good that, even eats up pump blades, and more. as the water turns to acid bam, damage.

it is not optional at all, why ever consider it is, is the true question?
if boil over the coolant in the engine you have a huge risk of warping the top cylinder head, or far worse. ever see the cost of that? $5 coolant over $1000+++ damage?

Tap + AF (50% you mix)
or AF in the jug premixed by maker of jug at 50%

your call
water ONLY TAP or any, even holy water ) is no good from 1926 up, back then radiators where huge just for water only cooling,
that is fact.
in fact car makers were then allowed to use smaller radiators due to the NEW better coolant that in fact, has better heat CONDUCTION 2x better.
see?
the engine must not overheat pulling a trailer, up a huge hill, on a 125F day. (that is one more fact)
the more you work an engine (using full power) the more heat it expells to the coolant) At idle , you can run beer at coolant. parked.
